AI agents call get_balance to retrieve information from Agenti without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries financial account data but does not move, spend, or commit funds. It is a pure read operation that retrieves current balance information. While the server context involves cryptocurrency operations, this specific tool only retrieves data without enabling any financial transactions or state changes. Confidence is high because the description is explicit and unambiguous about its read-only function.
From the tool's definition Tool description states 'Get USDC (Base) and SOL balances for a wallet' — a retrieval operation with no side effects. The verb 'Get' and the read-only nature of querying account balances are definitive.
Documented attack patterns abuse exactly the kind of access get_balance gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Agenti, and nothing reaches the server without passing your rules. This is the rule we recommend for get_balance:
{
"version": "1",
"default": "deny",
"tools": {
"get_balance": {}
}
}get_balance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get USDC (Base) and SOL balances for a wallet. It is categorised as a Read tool in the Agenti MCP Server, which means it retrieves data without modifying state.
Register the Agenti MCP server in PolicyLayer and add a rule for get_balance: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Agenti. Nothing to install.
get_balance is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_balance rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_balance. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_balance is provided by the Agenti MCP server (nirholas/agenti). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
